    This guide will show you how to pull codes for the ABS system if you have an ABS fault light showing on your dashboard.

    In order to do this, you will need to fashion a tool from a paperclip. That will allow you to "short" a diagnostic connector that will then blink the ABS light to give the fault code.

    1. Locate and unbend a paperclip so that the two ends are roughly the same length.

    2. Locate the diagnostic socket for the ABS. The socket is located in the passenger side footwell, underneath the glove box, it is a blue 5 wire connector, and usually clipped into a holder with no wires coming out of it.

    3. disconnect this 5 wire connector from the holder.

    4. With your paperclip tool, connect it to pins 5 and 3 of the diagnostic connector as show. Pin 5 is located on the far left, pin 3 is the 3rd in from the left, with the location tab on top.
    Also at this point make sure your ignition is turned OFF.

    5. Go around to the drivers side of the car. DO NOT press the BRAKE or CLUTCH pedal. Insert your key into the ignition and turn to position II. So that the dashboard lights illuminate, there is no need to start the engine.

    The ignition lights will come on as usual, as will the ABS light, the first time this comes on, is for a bulb test. After this the light will blink the codes stored for the fault.

    A long blink will indicate 10's and a short blink will indicate 1's. As in the case of the video below where I have simulated a fault the code is 13.



    6. Once reading is complete, turn off the ignition and remove your paperclip tool. To reset the ABS system, cycle the ignition 20 times.

      Your welcome mate. code 14, faulty sensor pulse. Ohm readings are not within spec. one minute below 2000ohm (where it should be) next minute way up to 3500 ohm. Might be a dirty sensor, or needing the sensor replaced.
